My sisters house was the same way. Instead of spending weeks trying to fish wire (The house is very poor designed for fishing new wire), we opted to run all the circuits through a GFCI outlet bank at the panel. The house only had 6 "outlet" circuits, so it wasnt bad. This was alot cheaper then all new romex and the time involved. We then changed all the outlets to grounded outlets and put the supplied "no equipment ground" on each outlet. My dad is a state certified electrician and said this is fine.
Grounding is done so that in the event that the hot wire touches the metal case of an appliance, the ground provides a return path to the breaker panel instead of you providing a return path to earth. The ground and neutral are connected at the panel and act as the same conductor. However, using a neutral as a ground is prohibited by NEC. This is because there must be a separate, unloaded return path (ground) in the event of a short to the case. This wuld ause a short circuit situation and blow the breaker. A GFCI does the same function to prevent electric shock. Devices that require an equipment ground (not really alot out there that does) may not function properly. My sister has never had a problem, in fact, she was saved by the gfci when a device of heres failed.

This is probably not the way for most people to handle this situation, but it was perfect for my sister's case. You can also buy GFCI circuit breakers, but the $10 GFCI outlets were alot cheaper then the $70 CGFI breakers.
